A former Mesa bank branch manager has been convicted on multiple federal charges after prosecutors proved she siphoned hundreds of thousands of dollars from the institution she was entrusted to oversee.
Brooke McDonough, 35, was found guilty following a two-week jury trial in federal court in Phoenix. The convictions include embezzlement by a bank employee, transactional money laundering, and structuring cash deposits to evade federal reporting requirements. McDonough managed a Mesa bank branch from 2020 through early 2022, a role that gave her access to both ATMs and the branch’s vault.
According to trial evidence, McDonough began stealing cash in mid-2021, removing money directly from ATM machines and the vault. Rather than depositing the funds all at once, she allegedly dispersed the cash across multiple ATMs and bank branches, deliberately keeping deposits below the $10,000 threshold that triggers mandatory currency transaction reports.
Prosecutors detailed that between June 2021 and February 2022, McDonough took approximately $655,000 from the branch and deposited or spent nearly the same amount during that period. The pattern of smaller, repeated deposits was central to the government’s case, demonstrating an effort to conceal the source of the money and avoid scrutiny.
Federal officials emphasized that the verdict underscores the serious consequences for financial professionals who abuse positions of trust. Investigators from the Federal Deposit Insurance Corporation’s Office of Inspector General worked alongside the Mesa Police Department to build the case, highlighting a coordinated effort to protect the integrity of federally insured financial institutions.
The prosecution was handled by Assistant U.S. Attorneys from the District of Arizona. McDonough now faces sentencing at a later date, where she could receive significant prison time and be ordered to pay restitution.
